Navis Clashes

[jmerch]

I have a couple questions.

1. I’m running into a time consuming issue.  I run my clashes and organize them...so the main folders would be something like HVAC vs Plumbing.  then in the results, I also organize the clashes in folders by areas of this job.  So all is good and back and forth in coordination I see the clashes get resolved.  Then once in a while what happens is all active clashes become cleared/resolved, and a new list of clashes populates.  Nothing moved or changed.  and any clashes that were remaining in my subfolders become "Resolved" but the new clashes are ones that were previously sorted and now I have to sort again.

2. has anyone come across an easy way to sift through duplicate clashes?

3. has anyone found an easy way to run clashes on certain areas of your drawing without doing a selection set?  or is there an easy way to sort the Clash Point column at least?  I have yet to find an easy way.

Hi there

I feel your pain.

I just purchased Jason Dodds new book Mastering Autodesk Navisworks Manage 2012. Its a good read. Highly recommended.

I've seen this from time to time.  For clashes to be recognized between sessions, the uniquely identified individual elements must be the same.  With some programs changing a part/component/object actually creates a new one rather than modifying the existing one: ergo, old clash is gone and a new one is found.  Sometimes users copy/paste or WBLOCK to a different file, resulting in a translation of object identities; ergo, old clash is gone and a new one is found.

The settings in different sessions of Navisworks (include/exclude XREFs, merge objects, append vs. merge, etc.) when the source files are created *may* create additional instances where the original clashing objects are no longer there.

I'm not sure there is a means of conveniently identifying objects uniquely and independant of replacement across the broad range of file types Navisworks can handle.

Thanks dgorsman that's correct.

It's one of the areas we're looking at improving at the moment but the best way to work through duplicate clashes is to right click the item in Tree View in the results tab and Group the clashes involving that item. Although it won't resolve the issue of getting these duplicates, it may help you work through them in a more deliberate way
